I'm planning to have all the game assets accessible, all of them will be in common formats (png, dds, plain text, json or sqlite database) or at least in the default engine specific formats (like models in bam or egg) so modding will be easy. If anyone is willing to back-port the cloths from the game back to MH, then I'm all for it.

One of the things I still need to make for the game is a werewolf morph and I'm willing to provide the model for anyone willing to make a MH target out of it (I'm not modeling it in Blender, so all I can provide is a obj or fbx and hope that the vertex order is preserved) - but I first need to make that morph, and I haven't started yet.

The walk is from mocap data, but heavily edited. I left the original rhythm of the legs and arms movement and basically made the rest by hand (head, spine, hips, palms, feet ... boards-with-nails) then edited the hell out of it so the feet stay on the ground and the whole animation loops (there's still one 'dead' frame at the end, but the game engine interpolates between the first and last frame so it still looks ok).
